The present invention relates to a system for measuring a thrust comprising: a first pressure sensor included in a thruster for generating a thrust and arranged at a position of introducing fluid into the thruster; a second sensor included in the thruster and arranged at a position of discharging the fluid from the thruster; and a calculation part for calculating the thrust of the thruster using a pressure difference measured by the first pressure sensor and the second pressure sensor. The system for measuring a thrust according to the present invention can maximize the efficiency of navigation control by calculating a velocity difference using a pressure difference in front of and behind a propeller and accordingly grasping a thrust generated by the propeller in the thruster including a duct and the propeller placed in the duct. The system for measuring a thrust according to the present invention can ensure the accurate value of the thrust even while a drillship moves as pressure sensors are installed in front of and behind the duct and the thrust is calculated through input values using Bernoulli′s principle.

    본 발명은 추력 계측 시스템에 관한 것으로서, 추력을 발생시키는 추진기에 구비되어, 상기 추진기에 유체가 유입되는 지점에 구비되는 제1 압력센서; 상기 추진기에 구비되어, 상기 추진기로부터 유체가 배출되는 지점에 구비되는 제2 압력센서; 및 상기 제1 압력센서 및 상기 제2 압력센서를 통해 도출되는 압력차를 이용하여 상기 추진기의 추력을 계산하는 계산부를 포함하는 것을 특징으로 한다. 본 발명에 따른 추력 계측 시스템은, 덕트와 덕트 내부에 위치하는 프로펠러를 구비하는 쓰러스터에 있어서, 프로펠러의 전후 압력차를 이용하여 속도차를 도출하고, 이를 통해 프로펠러에 의해 발생한 추력을 파악함으로써, 운항 제어의 효율성을 극대화할 수 있다. 또한 본 발명에 따른 추력 계측 시스템은, 덕트의 전후로 압력센서를 설치하여 압력값을 통해 베르누이 원리를 이용하여 추력을 계산하는 방식을 사용하는바, 드릴십이 이동하는 과정에서도 정확한 추력값의 확보가 가능하다.
